Issue Description
After a user configures the folder redirection function, logs in to the VM, and opens a file, a security warning dialog box is displayed.

Alarm Information
Handling Process
Configure the group policy to add a whitelist.

In the Group Policy Management Editor window, choose User Configuration > Administrative Templates > Windows Components > Attachment Manager. Enable the Inclusion list for low file types policy. In the Options area, enter the file name extensions to be added to the inclusion list, for example, .lnk, .exe, and .gif.

In the actual scenarios, no warning message is displayed if .lnk, .exe, and .msc are entered in the Options area. This operation does not affect other application functions.

Root Cause
Security levels for files in different formats are set in Windows file manager. If the file manager detects that a file that may not secure, it will forbid you to open this file, or displays a warning message before you open the file.
